Today we are beginning to test a new way for you to discover and buy products on Twitter. For a small percentage of U.S. users (that will grow over time), some Tweets from our test partners will feature a “Buy” button, letting you buy directly from the Tweet.

After tapping the “Buy” button, you will get additional product details and be prompted to enter your shipping and payment information. Once that’s entered and confirmed, your order information is sent to the merchant for delivery. Your credit card is processed securely and won’t be shared with the seller without your permission.

Here’s how it looks on mobile:

Twitter has partnered with Fancy, Gumroad, Musictoday and Stripe to build the button, and as usual the new feature has only been made available to a select few partners (and users) in the U.S., which includes brands such as @burberry, @homedepot and @RED, as well as celebrities such as Demi Lovato, Pharrell and, uh, Megadeth. So it’s essentially in beta test mode right now.
